CHIN-REST v Filed Oct. 17, 1954 Elmo/whorl APH M Jam Patented Aug. 31, 1937 1 UNITED STATES PATENT OFFICE CHIN REST Perry M. Johnson, Vassar, Mich.

Application 1 Claim.

This invention relates to chin rests which are designed to be used by embalmers to support the chin of a cadaver particularly during the embalming operation, which forces fluid under pres- 5 sure through the arteries and veins of the corpse, and among other objects, the invention aims to provide an improved device of this character having the advantages which will be hereafter pointed out.

In the accompanying drawing showing a preferred embodiment of the invention,--

Fig. 1 is a plan view of the improved chin rest;

Fig. 2 is a side elevation of the same;

Fig. 3 is a section on line 3-3 of Fig. 1 but'on 15 an enlarged scale; and

Fig. 4 is an enlarged end view of the curved metal strip forming part of the chin plate.

Referring particularly to the accompanying drawing, there is shown a chin rest which com- 20 prises a shank 5 preferably curved for the greater part of its length, as shown in Fig. 2 and being screw-threaded or otherwise removably secured to the chin plate 6. A crossbar I is adjustably secured on the shank 5 and extends at right an- 25 gles to said shank and carries a pair of shoulder braces 8 at its opposite ends. As shown, the shoulder braces have curved extremities so as to fit over the shoulders of the cadaver and they are preferably hinged tothe extremities of the crossbar l. Preferably, said extremities are offset, as shown in Fig. 3, so that the braces may move freely without pressing on the cadaver. If desired, the shoulder braces 8 may be adjustably mounted on the crossbar 1 by any well-known 5 means.

Preferably the intermediate portion of .the crossbar 1 is enlarged as indicated at 9 and has a curvature substantially the same as the curvature of the curved portion of the shank 5, as is 40 clearly shown in Fig. 2, and on said enlarged portion 9 a spring I is mounted so as to engage with the under side of a detent H. The detent is pivotally mounted between a pair of ears l2 secured to the enlarged portion 9 and one end of said detent is enlarged to provide a thumbpiece Ila and the other end is enlarged as at N17 to engage in one of a series of notches l3 formed in the curved portion of the shank 5. As the curved shank is interposed between the October 1'7, 1934, Serial No. 748,715

detent and the enlarged portion 9 of the crossbar, the detent will hold the shank adjusted relative to the crossbar and hence will permit adjustment of the chin plate and shoulder braces so that the device will be ent cadavers.

The chin plate 6 is close the chin of a very prises a curved metal plate a rubber l between which adaptable to many differ- 5 made large enough to enlarge cadaver and com- I4 having end notches band or an elastic 10 textile band 16 is stretched.

yield as the device is achment of the chin plate The elastic band will tightened and the chin of the cadaver enters the space between the ends of the plate 6. The purpose is to prevent marking and also to prevent sli chin. The described advantage that it doe of this rubber band of the flesh of the cadaver pping of the device on the device has the additional s not close the arteries by 20 improper engagement with the cadaver and hence permits flow through all portions This is because of the 8 with the shoulders.

Having described one embodiment of my invention, what I claim as new and by Letters Patent is:--

the character described comprising, a shank which is straight for a length and which is curved A device of in combination, minor fraction of its desire to secure for the remainder of its length; a series of notches formed in the crossbar movable pressed detent curved portion of the shank; a
